Not to be rude, but this is elementary school. How would anyone know this?
Answer:
a) We know that atleast one or more author writes a book.
Symbol to indicate one or more is (B)
So the correct option is B
b) We know that zero to multiple books are written by any author.
Symbol to indicate zero or more is (A)
So the correct option is A
c) The fourth option is correct if we replace by many to many relationship and generate a new entity.
So the relationship betweem author and contract is one to many. So we know that there is atleast one author that represent in symbol d and books has atleast 0 that represent in symbol c.
So Fourth Option is correct d at blue side and c at red side.
d) There are two forirgn keys in table Contract one is from AuthorId and other is ISBN.
So correcct option is C
Answer:
Option A:
<input name="name" id="id" type="number" value="value" step="value" min="value" max="value" />
Explanation:
Spinner control is a graphical control element where user can adjust the value by pressing up or down arrow button. An example is given in the attached image.
In HTML, one of the key attributes we must use to create a spinner control is "step". The attribute "step" is required to specify the interval of the step value when user press the up or down arrow button.
If we set the attribute values as follows:
- type = "number"
- value = 2
- min = 0
- max = 10
The setting above will give a spinner control with a range of legal numbers between 0, 2, 4, 6, 8 and 10.
Answer:
Below are the program for the above question:
Explanation:
#include <stdio.h>//header file.
int main()//main function.
{
int value; //variable declaration.
printf("Enter a number to find its roman value: ");//render a message for the user.
scanf("%d",&value); //take a value from the user.
switch(value)//switch case starts
{
case 1:
printf("I");
break;
case 2:
printf("II");
break;
case 3:
printf("III");
break;
case 4:
printf("IV");
break;
case 5:
printf("V");
break;
case 6:
printf("VI");
break;
case 7:
printf("VII");
break;
case 8:
printf("VIII");
break;
case 9:
printf("IX");
break;
case 10:
printf("X");
break;
}//switch case ends.
return 0;//return statement.
}
Output:
- If the user inputs as 4, then the output is "IV".
Code Explantion :
- The above code is in c language, in which the scanf function is used to take the inputs from the user.
- Then the value match from the switch case and display the suitable result.
- And the user get the roman value from the user.
